I updated the Woody block and noticed there are quite a few new things there. In order to implement the <wt:class> and <wt:new> tags I extended JXTemplateGenerator to support dynamic evaluation of custom tags. I just checked in this update. See the documentation. The attached file contains implementations of all of the <wt:xxx> tags including class, new, union, case and struct.

The attached fixes a couple of bugs and adds the wt:continuation-id tag. I've tested it with all the forms/{1}_template.xml examples in the woody samples.

Attached is a first attempt to implement the behavior of the Woody template transformer with the macro facility of the JXTemplateGenerator.
